Need a reliable seal between your cylinder heads and your headers or factory manifolds? Speed Engineering's MLS (multi-layer steel) exhaust manifold gaskets are engineered for extreme cylinder pressures, maintaining torque set and resisting corrosion without burning through or pushing out. No sealants required. These gaskets work across virtually any combination of cylinder head and exhaust manifold materials, making them compatible with Speed Engineering headers or factory exhaust manifolds. Sold in pairs — one for each bank.

Frequently Asked Questions:
Q: Do I need sealant with these gaskets?
No. These MLS gaskets are designed for direct installation without any additional sealants or sealing compounds.
Q: Will these gaskets work with my factory exhaust manifolds?
Yes. These gaskets are compatible with various combinations of cylinder head and exhaust manifold materials, working equally well with Speed Engineering headers or factory exhaust manifolds.
Q: How many gaskets are included?
This package includes 2 gaskets — one for each bank.
Q: What LS engines are these gaskets compatible with?
These gaskets are compatible with the full LS engine family including LS1, LS2, LS3, LS6, LS7, LS9, and LSX.
Q: What vehicles use this gasket?
This gasket fits a wide range of LS-powered GM vehicles including the Camaro, Firebird, Corvette, GTO, CTS-V, G8, Tahoe, Yukon, Escalade, Hummer H2, Avalanche, Silverado, and Sierra. See the full applications list for specific model years.
Q: What makes MLS gaskets better than standard gaskets?
Multi-layer steel construction maintains torque set under extreme cylinder pressures and resists corrosion, without burning through or pushing out over time — common failure points for lower-quality composite gaskets.
